| Abstract | Under the different light irradiation, the reflective and scattering intensity of skin image can be applied to evaluate many human health indices, such as oxygen saturation in blood, skin tissue aging or skin lesions (leukoplakia, turmoil cell, and so on). Due to the different absorption and scattering rate of skin illustrated by a variety of LED light source, we can perform the processing and analysis of skin surface images. Since the surface roughness is more sensitive to the shorter wavelength light source (430 nm and 470 nm LED), so the difference of reflective light image can be used to detect the skin roughness. In addition, the oxygenated hemoglobin (HbO2) in blood has a relatively high absorption rate at green (570 nm) and near-infrared (940 nm) light, so it can be used to compute the oxygen saturation. In this study, based on the different light absorption of HbO2 in blood, there are six light sources (deep blue, blue, green, deep red, NIR, white light) would be applied to the inspection of skin characteristics. The processed images provide better reference for the follow-up studies on the oxygen saturation of peripheral blood and skin aging. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
